In order to optimize the chain, we need to add content to the key link, that content if you add links, how to add it?

Parameter two: Replacement times

Return Result: Processed content

Header ("Content-type:text/html;charset=utf-8"); Set encoding

$linkdatas =array (

Array (' Front-End development ', ' http://blog.kgula.com '),

Array (' Front design ', ' http://blog.kgula.com '),

Array (' Web Front end ', ' http://blog.kgula.com '),

Array (' Front-End blog ', ' http://blog.kgula.com '),

);

echo "replace before <br/>";

echo $str = ' Web front-end development-focus on site front-end design and Web user experience. Front-End development, focus on the Web front-end development, focus on the Web user experience, focus on the latest and best front-end design resources and front-end development Technology professional front-end blog ';

echo "<br/> replace <br/>";

echo $str =keylinks ($STR, 2);

/**

* Associated keyword Replacement

* @param txt $string original string

* @param replacenum $int replacement times

* @return String returns strings

*/

function Keylinks ($txt, $replacenum = ' ") {

Global $linkdatas;

if ($linkdatas) {

$word = $replacement = Array ();

foreach ($linkdatas as $v) {

$word 1[] = '/(?! (<a.*?)) ' . Preg_quote ($v [0], '/'). '(?!. *</a>)/s ';

$word 2[] = $v [0];

$replacement [] = ' <a href= '. $v [1]. ' "target=" _blank "class=" Keylink ">". $v [0]. ' </a> ';

}

if ($replacenum!= ') {

$txt = Preg_replace ($word 1, $replacement, $txt, $replacenum);

} else {

$txt = Str_replace ($word 2, $replacement, $txt);

}

}

return $txt;
